For general pneumatic and water
piping in environments exposed
to sparks from arc welding, etc.
Fixed end
Note 1) Applicable for general industrial water. Please consult with SMC if using for the other kind
of fluid. Also, the surge pressure must be under the maximum operating pressure.
If the surge pressure exceeds the maximum operating pressure, it will result in damage to
fittings and tubes.
Note 2) The minimum bending radius is the representative value measured as shown in the left
figure. Allow extra length when piping since the tube may be bent if used under the
minimum bending radius.
Note 3) The color of all inner tubes is black.

Bend the tube into the U-form at a
temperature of 20°C. Fix one end and
close loop gradually. Measure 2R when
the deformed ratio of the tube diameter at
bending reaches 5%.
